assignor to Elmo Bernardasci, Gordola, Ticino, Switzerland, a Swiss citizen Filed Sept. 24, 1963, Ser. No. 311,254 4 Claims. (Cl. 162-394) This invention relates to means for manufacturing paper and refers more particularly to an apparatus for making filigreed Holland paper with all-sided edges.

An object of the present invention is the production of filigreed Holland paper with water marks and all-sided edges 'by the use of machines.

Another object of the present invention is to provide a machine-operated process which did not exist in prior art and by means of which it would be possible to produce filigreed paper of this type even in small quantities, such as 100 sheets at a time, in an economically feasible manner, the sheets being provided with a genuine water mark.

A further object is the provision of a paper-manufacturing procedure of this type, wherein the pattern for the water mark can be changed by simple manipulation without it being necessary to stop the machine for any lengthy time periods.

Other objects of the present invention will become more apparent in the course of the following specification.

In accomplishing the objects of the present invention it was found desirable to provide a periodically actuated ladle device cooperating with a track. The ladle device comprises a ladle mould which can be raised from and lowered into a vat and which is provided with a sieve frame used to apply the wet paper sheet upon the track; the ladle device also includes means for moving the ladle mould periodically perpendicularly to the track. The width of the track is at least as great as the width of the sieve frame and of the wet paper sheet. The track is connected with a drive which shifts it discontinuously and periodically in the direction of its length. The track remains immovable While the wet paper sheet is applied to it by the sieve frame whereupon, after the sieve frame is withdrawn, the track is moved forward by a stretch which is at least equal to and preferably greater than the length of the wet paper sheet which has been applied to it. Then the operation can be repeated.

The invention will appear more clearly from the following detailed description when taken in combination with the accompanying drawings showing, by way of example only, a preferred embodiment of the inventive idea.

In the drawings:

FIGURE 1 is a side view showing diagrammatically an apparatus of the present invention.

FIGURE 2 is a section through an interchangeable sieve frame.

FIGURE 3 is similar to FIG. 2 but shows the sieve frame in a different position.

The apparatus of the present invention includes three major devices, namely, the combined ladle and applying device, the pressing device and the paper carrying machine with a wiper and a collecting container.

As shown in FIG. 1, the combined ladle and applying device includes a ladle mould 2 connected to an oil pressure container 1 and carrying an exchangeable sieve frame 3. The ladle mould 2 is enclosed by a vat 4 filled with paper pulp.

The pressing device includes a press 8 having a counter plate 9 for squeezing moisture out of a paper sheet.

The paper carrying machine includes an endless band 6 consisting of felt or the like, which is guided by rollers 7 and cylinder 10 and which passes under plates 5 and 9. A wiper 11 and a collecting container 12 are located adjacent the cylinder 10.

In operation, oil under pressure supplied to the container 1 is used to move upwardly the ladle mould 2 by any suitable means not shown in the drawings. The ladle mould 2 carries the sieve frame 3 which is immersed in paper pulp located in the vat 4 in the inoperative position of the ladle mould. Thus a wet paper sheet is re moved from the paper pulp by the sieve frame. A suction device not shown in the drawings is located within the ladle mould 2; during the upward movement of the mould this suction device exerts suction upon the wet paper sheet so as to remove a certain amount of moisture therefrom. At the end of the upward movement of the ladle mould, the paper sheet is pressed against an undersurface of the felt band 6 which will be engaged by the plate 5 located directly above the band 6 and the ladle mould 2. Thus the paper sheet is impressed upon the band 6. Then the ladle mould 2 and the sieve frame 3 are lowered to their initial position. The endless band 6 carrying the paper sheet which has adhered thereto, is then moved by any suitable means not shown in the drawings, until the paper sheet is located above the press 8 said directly below the counter plate 9. The extent of movement of the band 6 must be greater than the length of the paper sheet measured in the direction of the endless band. While the band is at a standstill, the press 8 is actuated, so that a large amount of remaining moisture is pressed out of the paper sheet by the action of the press 8 which exerts pressure against the paper sheet, the portion of the band 6 which carries the paper sheet and the counter plate 9. Then the band 6 is again actuated and the paper sheet is moved by the band 6 over a major portion of the circumference of an electrically heated drum 10. The paper sheet is then completely dried. It is removed from the band 6 by the wiper 11 and drops into the collecting container 12.

It is apparent that the ladle mould 2, the press 8 and the band 6 may be driven by any suitable conventional means (not shown); it is important, however, that they should be operated in proper sequence in the manner set forth above.

The sieve frame 3 which is shown in greater detail in FIGS. 2 and 3, carries a lower sieve sheet 22 of steel wiring and an upper sieve sheet 23 of Phosphor bronze. A pattern 24 for any desired water mark is glued upon the sieve sheet 23. An iron rod 25 located below the sieve frame 3 is connected therewith by side arms 26. A shaft 28 carried by the ladle mould 2, carries a cam disc 27 which is keyed upon the shaft 28 and is located under the rod 25.

In order to exchange a pattern, the user turns the cam disc 27 clockwise (looking in the direction of FIGS. 2 and 3), until it is moved into the position shown in FIG. 3. In this position the cam disc 27 has raised the sieve frame 3 from the edges of the Walls 29 of the ladle mould 2. Then the sieve frame 3 can be easily grasped by the hand of an operator and removed. The operator can then place another prepared sieve frame carrying the pattern of another water mark upon the ladle mould and turn the cam disc 27 in the opposite direction until the cam disc has moved back to the orginal position shown in FIG. 2 in which the new sieve frame is held firmly by the engagement of the hook-shaped portion of the cam 27 with the rod 25 of the sieve frame.

The cam 27 can be rotated by any suitable means, namely, by hand, mechanically, hydraulically, pneumatt cally, electrically, etc.

This construction makes it possible to replace the water mark pattern 24 carried by the sieve frame 3 outside of the machine in such manner that the replacement of the pattern will not interfere with the operation of the machine.

It is apparent that the example described above has been given solely by Way of illustration and not by way of limitation and that it is subject to many variations and modifications within the scope of the present invention. All such variations and modifications are to be included within the scope of the present invention.
